OTOH, the current default exists since Emacs 21, so it sounds like a
reasonable default as well.

And I don't think arguing about defaults in Emacs is useful, because
changing the default if you don't like it is easy.  We do change the
default behavior slowly, though.

(And please note that we are talking about defaults for a feature that
doesn't yet exist, which makes this dispute even less useful.)

You'd invoke it when you either know in advance you don't want the
next character to ligate, or after you saw the ligature to disable the
ligation for the sequence at or before point.

Emacs cannot, but the user can.  Thus a separate command.
